ShaftSpacer® is a plastic spacer wheel guide and alignment system for lateral positioning and centralization of rebar reinforcement cages within caissons, drilled shafts and other geotechnical construction applications. Positioning rebar within specified clearances is critical. Our line of Shaftspacer® rebar spacer wheels ensure appropriate spacing requirements are met and rebar is centralized during the installation of the pile cage and throughout concrete placement.


WHY USE IT?

In order to ensure fabricated rebar cages are properly positioned for concrete placement every time. The ShaftSpacer aligns and centers rebar cages within the drilled shaft — providing proper clearance between the rebar cage reinforcement and the interior side walls of the shaft or casing.

APPLICATIONS

  • Bridge Foundations
  • Building Foundations
  • Retaining Wall Foundations
  • Street Light Foundations
  • High Mast Foundations
  • Transmission Line Foundations
  • Sub-station Foundations
  • Tower Foundations
  • Slurry Walls
  • CONSTRUCTION BENEFIT

  • Ensures the bar reinforcement is properly spaced and aligned within the confines of the drilled shaft or excavation
  • Provides quality assurance of the sub-contractor’s performance for the contractor and owner
  • Provides quality assurance of the contractor’s performance for the engineer and owner
  • Installs quickly and easily, requiring only unskilled labor
  • Increases job profitability because skilled labor is released for more demanding tasks

  • ADVANTAGES

  • Saves time & money on site
  • Easy to install
  • Lightweight, yet strong, durable
  • Engineered with the contractor in mind
  • Made of high-density plastic, resistant to corrosion, and chemicals common to construction
  • Excellent guide system for placement of fabricated rebar cages into drilled or excavated shafts
  • Economical with minimal installation costs
  • Indefinite shelf-life and easily stored

    READY TO GET STARTED ON YOUR NEXT PROJECT?

    BARBOOT® is a simple and economical means of supporting and spacing rebar reinforcement vertically at the base of drilled shafts. BARBOOT® plastic rebar supports stabilize the entire rebar cage vertically within the drilled shaft and provide proper clearance between the reinforcement cage and the earthen surface. An additional advantage of rebar reinforcement boots is that the encapsulation of the ends of the vertical rebar provides added corrosion protection.

    BARBOOT® rebar supports provide quality assurance for the contractor of the subcontractor’s performance. At the same time, it provides quality assurance for the engineer and owner of the contractor’s performance.
